The Sultan and the Storyteller by Lichelle Slater

For thirty-nine nights, the sultan of Zunbar has chosen a new wife.
For thirty-nine dawns, they are pronounced dead.
When Sultan Zayne summons my best friend to be taken as his newest victim, I can no longer pretend to be blind and volunteer in her stead. My only plan–weave a story each night and hopefully learn why he would kill in the first place.
As I unravel the tapestry of lies, I learn there’s more going on inside the gilded walls of the palace than anyone in the land could ever realize. I’ve woven myself into the story, and if I don’t pull on the right thread, it’s not only my life at stake but my heart.
